Why are the forces important when building a plane
Answers
Answer:
An airplane in flight is acted on by four forces: lift the upward acting force; gravity, the downward acting force; thrust, the forward acting force; and drag, the backward acting force (also called wind resistance). Lift opposes gravity and thrust opposes drag.
Perhaps the most important force to a pilot is lifted. Lift directly opposes the weight of the aircraft to keep it aloft. As the aircraft moves faster, lift increases until its force is equal to the weight. When the equilibrium between weight and lift is established, the aircraft is pushed upward.
These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. Wings keep an airplane up in the air, but the four forces are what make this happen. They push a plane up, down, forward, or slow it down.
